Commenting on TVB general manager Stephen Chan Chi-wan, who was this week cleared of corruption and fraud charges, Ko, who's signed to the station, said she hadn't had a chance to congratulate him in person.

'I don't have his number so I couldn't call him, but I feel very happy for him,' Ko said. 'I think he's a very friendly and capable boss. I respect him a lot. But I think the best I can do at this point is work harder to prove myself to the audience.'
